i always catch recommendations from the help desk librarians. Some of the best books I've read I'd never have picked up otherwise. We were chatting about it and they decided to plug in the books I gave good feedback for, just to see.

It was a comical five minutes.

Seems like a good response to be honest- patron asks for non existent book, librarian informs them it doesnt exist, patron persists, librarian asks AI to write a 100page book with the requested title, then sends the patron the output.

Oh but they try, and people for some reason still mostly use them as search engines.
